Why is my hyundai sonata not accelerating?
If your Sonata is too low on transmission fluid, it’ll will no longer be able to transfer power to the rear wheels. The power goes to the torque converter, and that’s the end of the line.

Why did my Hyundai Sonata engine die while driving?
I have a Hyundai Sonata 2002 automatic which has just broken down. What happened is that while driving the engine suddenly stopped and the check engine light turned on.

Why is the timing chain on my Hyundai Sonata not working?
The timing chain (or belt) is responsible for keeping the upper valve train synced with the crankshaft. This is vital for spark timing. If the timing is off a little and the engine still runs, the timing belt may have skipped. If it has jumped too much the Sonata may not even fire.

Key Immobilizer faulted (unlikely unless you’re using a non-standard key or bypassed it for a remote starter or some crazy electrical nonsense). If it is this, to replace the immobilizer unit and/or keys could be around $300 or so. Crank Angle / Crank Position / Cam Angle / Cam Position sensor (s).

When to replace PCV valve on Hyundai Sonata?
I’m critical of the oil & lube establishment for not suggesting replacement of the PCV valve the first time the vehicle came in low on oil.

In fact it really can be normal for an engine to use oil at this rate.
